The East Bay Rats, a legendary motorcycle club in Oakland offers an innovative solution to barroom brawls – Fight Parties. Since 1996, the club has organised Friday Fight Nights – putting potential troublemakers (and anyone else who volunteers) in a boxing ring at the clubhouse and giving them a chance to work the violence out of their system.

According to East Bay Rats founder Trevor Latham, everybody has a violent streak in them and Fight Nights give people a safe space to test the limit of their courage. “Why not?” he asked. “The worst that can happen is you get a bloody nose.”

Over the years, Friday Fight Nights have become insanely popular, with the courtyard around the ring jam packed with spectators. Everyone who wants to fight gets a chance – it’s usually guys vs. guys and women vs. women, but you don’t have to be a professional fighter to get into the ring. Participants range from bartenders and photographers, to bodybuilders, college students, lab technicians or musicians. That’s what this tradition is all about – real fights between real people.

It’s called Friday Night Throwdown, but most know it as the male model fight club, an unlicensed underground event that puts pretty boys in the ring with street fighters and real boxers. As you can imagine, models almost never win.

“I think it’s hilarious that the whole point of their being is to make money off what they look like, yet they’ll come throw down for a couple of hundred bucks,” one of the Friday Night Throwdown organizers says about the pretty boys who sign up to get their asses kicked for around $150. But for the people doing the fighting in the ring, the event is no joke. “I definitely tell everybody, ‘This is no bullshit. You’re about to get in front of 800 people. Get ready—and if you don’t, it’s still going to be entertaining for you to get your ass beat,’” the organizer says. And most of the models involved in this underground phenomenon take that advice very seriously. They train hard, and the fights have gotten more intense during the last two years that Friday Night Throwdown has been taking place in various downtown New York warehouses. It’s in the models’ financial interest to put up a good fight, because if the crowd likes them, they might get invited back and paid double or triple what they earned the first time. Still, despite their best efforts, only one male model has actually won a fight against a hardened fighter.
